    • defining RDF repositories.
    • querying, inserting, updating, and deleting RDF data.
    • defining namespaces for serialization purposes.
  • Provides management interfaces for:
    • repository management, listing the available repositories provided by add-on modules hooking into the RDF API.
    • data management, allowing the conjunctive graph of the available RDF repositories to be queried using subject, predicate, and object.
    • namespace management, listing all URI abbreviations used for CURIEs.
  • Provides theming functionality for:
    • property name-value tables from RDF data.
    • triple tables consisting of subject, predicate, object.
    • rendering URIs/literals in human-readable form (e.g. as CURIEs).
  • Provides serialization/unserialization for the RDF/PHP and RDF/JSON formats.
